Abstract
In this paper, a method to improve the sensitivity of the resonance mass sensor by incorporating PID controller is proposed. The controller is designed to retain the vibrating frequency of the resonator at its natural frequency with mass loading. The experimental results demonstrate that the resonant mass sensor with PID controller provides 18 times higher sensitivity as compared to the resonant mass sensor without controller.
